Question

curved surface area of a cylinder is 110 cm^2 and circumference of the base is 22cm find its heig

Answer 1

circumference of base = 22

2πr=22 ,

2×22/7r=22

44/7×r=22

r = 7×22/44

r = 154/44=14/4 curved surface area of cylinder= 2πrh

110 = 2×22/7×.14/4×h

110 =44×2/4×h

110=88/4×h

110=22×h

110/22=h

10/2=h

h=5
